RTSP DESCRIBE succeed, but SETUP command add /trackID=video that cause url size to be 131 in second case.

It looks like authenticated urls has limit for 130 chars.
Setting or not setting port in url doesn't affect as in RTSP requests ffmpeg always add port, but IP address affects. So having 192.168.0.245 instead of 192.168.0.8 reduce working path by 2 chars.
For not protected urls there are no such problem.
